Whisper bio bag Things to consider
Using a system of plastic and aluminum coated paperboard combined with an aseptic filling system, these cartons had the ability to be perfectly airtight. These initial cartons were tetrahedra, leading to the company's name: TetraPak, derived from "four" in the Greek languageIn nineteen sixty three (1963) the company introduced another one called TetraBrik, a rectangular cuboid carton. Later, more cartons were launched such as the tetrawedge which was wedge shaped and tetraprisma which was round octagonal and then there was the tetrafino which was a pouch shaped packaging. Some other tetra bio bags include tetrarex(gable top), tetratop(paper and plastic moulded in one) and the now discontinued tetraking. The tin culture has been opposed by the introduction of tetra bio bags for vegetables.
